I had to change permissions, and that took some jiggling, but I can open
and access the Tomcat folder, now
You may wish to add this to your documentation
And now, when I tried to start the Tomcat server from Eclipse (even though
it is running in Services)
I am seeing: The server cannot be started because one or more of the ports
are invalid. Open the server editor and correct the invalid ports.
I set the admin port to 8005.
After more searching, I stopped the Tomcat server in Services and tried to
start in eclipse.
omgosh, it worked. good grief.
and, thank you,
Stephanie

Help please. I have installed: Java EE, Eclipse and Tomcat.
When I try to connect the server, I encounter:
Unknown version of Tomcat was specified.
I am looking all over. please help
Java EE for web developers
C:\Users\steph> java -fullversion
java full version "17.0.6+9-LTS-190"
and
Eclipse IDE for Enterprise Java and Web Developers
Version: 2022-12 (4.26.0)
Build id: 20221201-1913
and
http://localhost:8080/
Apache Tomcat/10.1.7
If you're seeing this, you've successfully installed Tomcat.
Congratulations!
C:\Program Files\Apache Software Foundation\Tomcat 10.1
and Tomcat is running in Services
If you're doing development, you really do not want to run Tomcat as a
service.
1. Download the appropriate zip file from tomcat.apache.org
2. Unzip it in a place that you have R/W access
3. Add the runtime to Eclipse
in Window->Preferences->Server->Runtime Environments
a. click on the Add button
b. open up the Apache folder
c. browse to the version of Tomcat that you want
d. select it and click on the Next button
e. click on the Browse button and browse to where you unzipped Apache Tomcat
f. select the folder, leave the default names as is
g. click finish
Now, you'll need to create a new server based on the default runtime.
This is handy, because you can have several servers based on the default
runtime. You can run them on different ports, have one set up for
debugging, choose different JREs, etc.
1. Go to Window->Show View
2. Select Other
3. Type in Server in the search text
4. Select Servers
5. Click on the Open button
It will complain that you have no servers configured. I know, you're
going why? I configured a server runtime environment, so why no server.
That's because you can have several servers based on the same runtime
(see above).
So:
a. create a new server - opens up a Define a New Server dialogue.
b. open the Apache folder, and select the desired Tomcat version (same
as before)
c. give it a unique name in Server name: field
d. The server runtime environment should be populated with the one added
above
e. click on the Next button
f. this will show you a list of projects to add - since you don't have
any, just click Finish
Now you should see a new line in the Servers window that describes your
server. If you double-click on the line, you'll get a nice configuration
screen.
There are lots of things to tweak. However, you should note the following:
Server Path: .metadata\.plugins\org.eclipse.wst.server.core\tmp0
If you have more than one server, they'll be located in tmp1, tmp2, etc.
If you need to change anything besides the ports for your Tomcat server,
create the same directory structure that you see in Tomcat under the
tmpN directory:
bin
conf
lib
logs
temp
webapps
work
Note, you may only need to create what you need, and probably not
webapps. It's been a while, and I'm a NetBeans person, not an Eclipse
person.
You can add things like database drivers in the lib subdirectory. You
should be able to see logs in the logs directory. I recommend using
log4j2 in your applications (along with commons-logging) and log to the
${ sys:catalina.base}/logs directory.
You can also modify the launch configuration and add the database driver
jar that way:
a. click on Open launch configuration
b. select the Classpath tab
c. click on User Entries
d. Click on the Add External JARS.. button
f. Browse to the JAR containing the database driver and add it
You can now start, stop, and control whether or not the Tomcat server is
launched in debug mode, all from the IDE.
I hope this is not overwhelming. I worked through some of these while
writing this up, since I'm an Apache NetBeans person. I don't want to
get into an IDE war, but I just like NetBeans better.
. . . . just my two cents
